Structurally stable rotating light fields (spiral beams) are investigated for various values of the rotation velocity. We prove that, in general, the fields may be described in terms of quasi-analytic functions. Some examples of spiral beams are presented.
Key words: paraxial rotating light fields / phase singularities
